-Subject: [PATCH] Optimize Captured TileEntity Lookup
-
-upstream was doing a containsKey/get pattern, and always doing it at that.
-that scenario is only even valid if were in the middle of a block place.
-
-Optimize to check if the captured list even has values in it, and also to
-just do a get call since the value can never be null.
